摘　　要：研究新型槽口无黏结水平接缝(Rabbet Unbond Horizontal Connection, RUHC),有助于提高装配式剪力墙的抗震性能。文章模拟RUHC低剪力墙的低周反复加载,并对比分析平界面接缝(PJ)低剪力墙和现浇(XJ)低剪力墙的破坏形态、滞回性能、水平承载力、延性、耗能能力及刚度退化等抗震性能。结果表明:RUHC低剪力墙的损伤程度轻于PJ和XJ低剪力墙;相较于XJ低剪力墙,RUHC和PJ低剪力墙的滞回环相对较饱满;RUHC低剪力墙的屈服荷载、峰值荷载和极限荷载均大于PJ和XJ低剪力墙的,RUHC低剪力墙的延性及耗能能力比PJ和XJ低剪力墙的均有不同程度的提高;RUHC与PJ低剪力墙的刚度退化曲线走势基本一致,而XJ低剪力墙的刚度退化则较快。Investigating the seismic performance of prefabricated low shear walls with a novel rabbet unbonded horizontal connection(RUHC)can contribute to improving the overall structural resilience of assembled shear wall systems.This study conducts a low-cycle repeated loading simulation of RUHC low shear walls and compares their seismic performance with that of flat interface joint(PJ)and cast-in-place(XJ)low shear walls.The analysis focuses on failure modes,hysteretic behavior,horizontal bearing capacity,ductility,energy dissipation capacity,and stiffness degradation.The results indicate that RUHC low shear walls exhibit less structural damage compared to PJ and XJ low shear walls;Compared to PJ and XJ low shear walls,RUHC and PJ low shear walls demonstrate relatively fuller hysteresis loops,suggesting better energy dissipation.Furthermore,RUHC low shear walls outperform both PJ and XJ low shear walls in terms of yield load,peak load,and ultimate load.The ductility and energy dissipation capacity of RUHC low shear walls are also notably enhanced compared to the other two types.The stiffness degradation trends of RUHC and PJ low shear walls are largely similar,whereas XJ low shear walls exhibit a more rapid rate of stiffness degradation.
